Ingesting EC data to newly expanded storage nodes

Issue

  • Expand a grid with multiple new nodes.
  • While continuing to ingest EC data we observe that as data is put on the new nodes, it does not balance evenly to all newly added nodes.
    • Please note that data will never be completely evenly distributed. 
    • This issue is for drastically higher usage on some newly added nodes vs other newly added nodes. 
    • EXAMPLE: New Node 1 has 50% usage while other newly added nodes have 20% usage. 
  • Some new nodes appear to be getting utilized far more than others.
  • As ingest continues, the gaps between new node utilization continue to grow.
